Description

Vertical piece joint connection structure of mixed tower wind power prefabricated tower tube sheet Technical Field The utility model relates to the technical field of tower construction, in particular to a vertical seam connection structure of a tower pipe piece of a hybrid tower wind power prefabricated tower. Background With the promotion of the nation to the new energy field, the concrete tower has natural durability (corrosion resistance), can still keep the performance under extreme conditions, has low maintenance cost, and brings better generated energy compared with the pure steel structure tower with low investment cost, especially the concrete tower and the steel mixed tower with steel tower, the share of the concrete tower and the steel mixed tower in the ultra-high tower wind power market is gradually increased, and the advantages are more and more obvious. The wind power mixing tower structure is convenient to transport and assemble quickly, low in manufacturing cost and use and maintenance cost, capable of effectively enhancing stability and rigidity of the mixing tower structure after being stressed, and beneficial to prolonging the service life of the tower. Because the height of each section of pipe joint of the tower barrel of the mixing tower is about 4m, the wall thickness is 300mm, the outer diameter of the tower barrel at the lower part is larger, the tower barrel consists of two C-shaped pipe pieces or a plurality of pipe pieces, and vertical joints are connected through dowel bars and are grouted to form O-shaped pipe pieces. The vertical seam is reserved with a 20mm wide seam generally, and how to better increase the connecting effect and form the duct piece into an organic whole through grouting is the content of the important research in the field. Disclosure of utility model In order to better increase the connection effect between C-shaped duct pieces and form the duct pieces into an organic whole through grouting, the utility model provides a vertical seam connection structure for a wind power prefabricated tower tube piece of a mixing tower. The utility model provides a vertical seam connection structure of a wind power prefabricated tower tube sheet of a mixed tower, which adopts the following technical scheme: The utility model provides a vertical piece connection structure of tower bobbin piece is prefabricated to mixed tower wind-powered electricity generation, includes transverse bellows, pre-buried sleeve and connection dowel, and transverse bellows is horizontal pre-buried in the one end of section of jurisdiction, and pre-buried sleeve is horizontal pre-buried in the other end of section of jurisdiction, and connection dowel includes screw rod portion and mound head, and the diameter of mound head is greater than the diameter of screw rod portion, screw rod portion and pre-buried sleeve threaded connection, mound head insert locate in the transverse bellows. Through adopting above-mentioned technical scheme, connect dowel one end through the screw thread connection, the pier nose anchor of the other end has not only promoted joint strength and tensile pull-out performance, has still promoted constructor's convenience of operation, and then has promoted the efficiency of construction. Optionally, an anchor bar is fixedly connected to the embedded sleeve, and the anchor bar is connected with a reinforcing mesh in the duct piece. Through adopting above-mentioned technical scheme, promoted the steadiness of pre-buried sleeve in the section of jurisdiction.
